A great feature of advantage in this fo'i'iii ln carrying the invention inte effect a sheet of spout ovei' those in ordinary use is that 9S of steel er iron of the pi'epersize is taken and where the outer er fi'ont end of the spout is formed by suitable mechanism into the frusburned off the spout may be trued and a new tuin of a cone, and then the edges are joined head applied without the necessity ef employn ment of skilled labor for the purpose, and, further, there Will be but slight loss of time in effecting repairs. f

/Vhile the shell is herein described as being provided with beveled ends, it is to be understood that the invention is not to be limited to this arrangement, as the ends may be square. Furthermore, the heads of the spout may be arranged in parallelism, or the rear head may be disposed at an incline to the front head, or vice versa, as may be found necessary or desirable.

Having thus described the invention, what is claimed is- In testimony that I claim the foregoing as y my own l have hereto aEXed my signature in the presence of two Witnesses.
